No security is 100% and neither is my solution. Given enough time,
interest and computer time it could be hacked.
But we used similar tamper-proof credentials security on three large,
hacker-infested community web sites which together logged up to .75
billion page views/month. Everything else under the sun got hacked but
this encrypted cookie never was (we had watchdogs sniffing for mangled
cred cookies). It was just too much work.
